atelier tekuto: earth bricks

japanese architecture practice atelier tekuto has recently completed ‘earth-bricks’, a residential structure located in chiba, japan. the curved exterior wall is formed from 2,600 earth bricks comprised of a dense mixture of soil and magnesium oxide, an element which can be easily sourced from ‘magnesite mineral’, commonly found in oceans and land. originally used for the mortar joints of the pyramids and great wall of china, this structure aspires to reintroduce masonry construction sourced from local soil as a viable option for developing countries.

the stacked rectangular bricks are slightly angled to produce the undulating and faintly segmented perimeter enclosure. a deep roof overhang extends to screen a ribbon clerestory window formed with glass blocks of similar proportions to the custom soil-based units. at night, the dwelling softly glows through the translucent glazing of the fenestrations. upon entering the central living space and kitchen, attention is directed to the exposed structure of the vaulted ceilings. rafters radiate downward from the main ridge element, which is reminiscent of a spine. the curved stairway attached to the exterior wall leads inhabitants to an open bedroom loft with views of the great room below. the bathroom and storage room are concealed within a partition behind the food preparation area and underneath the wooden steps.

  • elegant and functional: great combination!

    lorena riba says:
  • Very intriguing design and fine execution. I assume the owner(s) sleep on the platform above the bathroom and kitchen? But except in the kitchen I do not see any cabinets or room for storage.

    airborn says:
  • congratulations

    geert-hugo says:
  • Ohhhh, I miss the cement . . . and the ubiquitous telephone pole . . . but, to keep me happy, they’ve given me the Swan ad next door. So, I suppose, if one wanted to go outside and sit in the garden, one could “think” swans instead of actually see them. Oh, those Japanese are clever.
    I like the building, but I don’t. Has the world gone
    mad?

  • Finally a Japanese home with warmth and texture. This is the coolest one I’ve seen in a while!

    Hats off to Atelier Tekuto! says:
